Momordica charantia L., also known as lianggua, is a medicinal and edible plant of the Cucurbitaceae family, native to the tropical regions of southern Asia. According to the Compendium of Materia Medica and the Materia Medica of Southern Yunnan, bitter gourd can clear heat, relieve summer heat, nourish blood and qi, nourish the kidneys and spleen, nourish the liver and improve vision. The Momordica charantia oligopeptides, which use Momordica charantia as raw material, use advanced biological enzymolysis technology to transform macromolecular proteins into small molecular active peptides with molecular weight less than 500 Da, not only completely retain all the nutritional essence of Momordica charantia, but also make its bioavailability and physiological activity significantly improved.
Application
Since Indian scholar Khanna first isolated the insulin-like active peptide-P (P-polypeptide, molecular weight 11000 Da, containing 166 amino acids) from bitter gourd in 1981, research on bitter gourd peptides has lasted for more than 40 years. Nowadays, Kpeptide bitter melon oligopeptides have become a star ingredient in the field of functional foods due to their ten core effects, including lowering blood sugar, regulating blood lipids, antioxidation, enhancing immunity, protecting the liver, anti-tumor, promoting wound healing, anti-inflammatory and antibacterial, improving sleep, and delaying aging.
1. Lowering blood sugar - the core mission of "plant insulin"
Lowering blood sugar is the most dazzling and clinically valuable effect, and it is also the fundamental reason why it is known as the "plant insulin".
(1) Insulin like activity, directly acting on insulin receptors
Confirmed by international authoritative journals "Agricultural Food Chemistry" and "Food Chemistry", bitter melon (especially Insulate)Bitter melon peptide, containing 68 amino acids and a molecular weight of 7346 Da,
has clear insulin-like activity and can directly bind to insulin receptors on the surface of cell membranes, opening up glucose transport channels and allowing glucose in the blood to enter cells for metabolic utilization, thereby rapidly reducing blood sugar.In vitro digestion experiments further confirmed that even when digested and broken down into smaller fragments (especially the 50-68 amino acid fragment mcIRB-19), it still maintains binding affinity with insulin receptors and oral activity is not disrupted by human digestive enzymes.
(2) Multi pathway synergistic hypoglycemic effect
Specific effects of the mechanism of action. Promote insulin secretion by pancreatic beta cells to improve insulin resistance and increase insulin sensitivity index. Activation of AMPK signaling pathway enhances glucose transporter activity and promotes peripheral tissue uptake of glucose.Inhibition of intestinal alpha.glucosidase inhibits starch degradation and reduces intestinal glucose absorption. Enhance liver glycogen/muscle glycogen reserves, improve glucose metabolism, and reduce blood glucose levels in mice with hyperglycemia.
(3) Clinical data support
Clinical studies have shown that daily intake of 200 mg balsam pear peptide can reduce fasting blood glucose by 15% -20%, especially for type 2 diabetes patients with postprandial blood glucose control effect is significant. At the same time, momordicin can effectively reduce glycosylated hemoglobin (HbA1c), and delay the occurrence of complications such as diabetes retinopathy and cataract. Special reminder: It are food grade ingredients and cannot replace hypoglycemic drugs. The existing clinical evidence is not enough to support its significant independent hypoglycemic effect on human body, and diabetes patients still need to follow the doctor's advice.
2. Regulating blood lipids and weight control - a leap from "lowering blood sugar" to "lowering blood lipids and losing weight"
(1) Comprehensive improvement of blood lipid profile
It can reduce plasma total cholesterol (TC), triglycerides (TG), and low-density lipoprotein cholesterol (LDL-C) levels,
while increasing high-density lipoprotein cholesterol (HDL-C) levels, fundamentally improving lipid metabolism disorders. The mechanism is that when insulin sensitivity increases, fat breakdown in the body decreases and lipid metabolism tends to normalize.
(2) Inhibit glucose absorption and regulate appetite
Inhibiting starch degradation can affect intestinal glucose absorption, stabilize postprandial blood glucose levels, shorten hunger duration, and prevent fat accumulation caused by overeating.
Even more ingeniously, bitter melon peptides can stimulate the secretion of GLP-1 (glucagon like peptide-1), enhance the body's satiety, suppress appetite from the source, and reduce food intake.
Animal experiments have shown that the expression levels of genes related to fatty acid synthesis can be reduced, while the expression levels of genes related to catabolism can be increased, which can help develop a "lean constitution" at the genetic level.
(3) Inhibit fat synthesis and promote fat breakdown
It can inhibit fat synthesis, promote fat breakdown, and help control weight, making it an ideal auxiliary method for people who want to lose weight.
3. Powerful antioxidant - a natural shield for clearing free radicals
It are rich in polyphenols and saponins, which can effectively scavenge hydroxyl radicals (· OH), superoxide anions (O ₂⁻ ·), and DPPH radicals. Research data shows that its antioxidant capacity is 3-5 times that of vitamin C, which can significantly reduce the levels of oxidative stress markers such as malondialdehyde (MDA) and protect cell membranes from oxidative damage. Free radical scavenging ability.
DPPH radical IC ₅₀=0.44 mg/mL, maximum clearance rate 79.04%. Superoxide anion (O ₂⁻·) IC ₅₀=0.86 mg/mL, maximum clearance rate 60.81%. Hydroxyl radical (· OH) IC ₅₀=0.85 mg/mL, significantly eliminated. Long term consumption of Kpeptide bitter melon peptides can help improve skin condition, reduce wrinkles and pigmentation, and achieve anti-aging effects from the inside out.
Enhance immunity - build a strong defense wall.
Its active ingredients can fully activate the immune system:
Stimulate macrophage proliferation, enhance their phagocytic ability, purify blood, and clear toxins; Enhance the activity of natural killer cells (NK cells) and strengthen the body's ability to clear viruses and abnormal cells; Promote the secretion of interferon - γ (IFN - γ), enhance Th1 type immune response, and have significant immune regulatory effects on individuals with recurrent respiratory tract infections;
Antiviral: It can inhibit the activity of pathogens such as influenza virus, meningococcal virus, and pneumococcus, reducing the risk of infection. Protecting the liver - dual guarantee of detoxification and repair.
(1) Reduce liver damage
By inhibiting CYP2E1 enzyme activity, liver cell lipid peroxidation is reduced, significantly lowering serum ALT and AST levels. Animal experiments have confirmed that it can alleviate alcoholic liver injury, improve the degree of liver fibrosis,
and also have a significant improvement effect on non-alcoholic fatty liver disease.
(2) Clinical data
Among 100 patients taking oligopeptides, 90 showed an increase in albumin (effective rate of 90%) and 92 showed a decrease in globulin (effective rate of 92%). It can enhance albumin, restore liver function, reverse liver cirrhosis and ascites.
(3) Prevention of fatty liver It can restore normal glucose metabolism, reduce the production of free fatty acids in the blood, and effectively prevent fatty liver and liver lesions.6. Anti tumor - a precise weapon for selective killing.
Scientific research has confirmed that it has inhibitory effects on the proliferation of differentiated gastric cancer cells AGS and MGC80-3, and its mechanism is related to inducing tumor cell apoptosis and regulating gene expression in the proliferation/apoptosis pathway. In addition, it can selectively kill choriocarcinoma cells and melanoma cells, exerting anti-tumor effects by inhibiting protein synthesis in tumor cells.
7. Anti inflammatory, antibacterial and promoting wound healing
(1) Broad spectrum antibacterial
It has significant inhibitory effects on Gram positive cocci (Staphylococcus aureus, Staphylococcus epidermidis), Gram positive bacilli (Bacillus subtilis), and Gram negative bacilli (Escherichia coli, Pseudomonas aeruginosa, Shigella,
Proteus mirabilis, Klebsiella pneumoniae, etc.), and is a natural broad-spectrum antibacterial agent.
(2) Anti inflammatory and analgesic effects
It can effectively inhibit inflammation in various organs of the body,
alleviate chronic inflammation such as arthritis and enteritis.
(3) Promote wound healing
It can upregulate the expression of epidermal growth factor (EGF), promote fibroblast migration and collagen synthesis. When applied to patients with diabetes foot ulcer, it can shorten the wound healing time by 30% -40% and reduce the formation of scar tissue.
8. Improving sleep, delaying aging, and whitening the skin
Some components in bitter melon peptides have sedative effects and can help improve sleep quality, especially beneficial for people with insomnia. Its strong antioxidant capacity, combined with its ability to promote cell repair, can delay the aging process from the source.
